title: [Clinical application of multidetector-row CT angiography for preoperative evaluation of nourished vessels of flaps].
abstract: OBJECTIVE
  To study the multi-row detector CT angiography (MDCTA) for preoperative evaluation of nourished vessels of flaps.
  
  
  METHODS
  Preoperative MDCTA was performed to obtain the anatomic information about the nourished vessels of flaps, including ceassel course, localization, diameter and number of perforator artery. Then the flaps were designed according to the MDCTA results. The postoperative results were observed.
  
  
  RESULTS
  From Aug 2006 to Aug 2007, 24 flaps (in 16 cases) were performed, including 10 flaps with deep inferior epigastric artery, 4 flaps with descending branch of the lateral circumflex femoral artery, and 10 flaps with thoracodorsal artery. The primary preoperative flap design was chaged according to the MDCTA results in 3 flaps. The distribution of the nourished vessels of flaps were exactly the same as the results of MDCTA. All the flaps were survived with satisfactory results.
  
  
  CONCLUSIONS
  MDCTA is a convenient and reliable technique for preoperative detection of nourished vessels of flaps. The MDCTA results can provide right and direct anatomic information for preoperative flap design to make sure the safety and good results of surgery.
